Cantina

Info

Library for processing signal input through a vocoder controlled by MIDI Input (carrier frequency and velocity, modulated by MIDI controllers and envelopes).

Build

State:

Working on Linux. Have issues linking to FFTW on Windows.

Dependencies:

• Pantoufle (submodule)
• SoundTouch 2.1.2
• FFTW3 3.3.8

On Debian:

sudo apt install libsndfile-dev vamp-plugin-sdk libsoundtouch-dev libfftw3-dev

To do

Features

Pitch shifting

• Set pitch of pitch sifter outside of the apply() routine.
• Make it vary incrementally with a Slider.

Misc

• Output freq / volume info of seed as MIDI note?
• Move responsibility of MIDI tone <-> frequency conversion to Eurêka when ready.
• Add support of phase-based pitch shifting with RubberBand.
• Implement mixed pitch shifting for semi-static pitch shifting to harmonics.

Fixes

• Audio signal frets when starting and stopping note. Testing revealed that it was not obviously related to velocity changes.
